该PFI：AIR技术转化项目的重点是转化低散热（LHR）和低温燃烧（LTC）的协同组合，以填补现有商用内燃机与清洁高效先进内燃机之间的技术差距。转化的LHR/LTC技术具有以下独特的功能：低温燃烧发动机的低散热，与传统或普通低温燃烧发动机相比，其导致更有利的热力学。与领先的竞争内燃机相比，这提供了示例性的效率、氮氧化物和固定碳的发动机排出废气排放以及用于废气排放控制系统的有利操作的合适的废气温度。该项目通过进行概念验证来实现其目标，该概念验证通过实验和计算在压燃式发动机中使用LTC实现LHR概念，从而在轻型汽车柴油发动机中运行原型LHR/LTC燃烧模式。该合作伙伴关系涉及通用汽车公司，该公司设计和制造原型轻型汽车发动机。通用汽车公司在全球汽车市场领域提供指导，如操作限制、成本限制和与适销产品的技术集成，以使LHR/LTC燃烧沿着一条可能导致竞争性商业现实的道路发展。潜在的经济影响预计在未来10年内将接近4000万美元（基于美国新柴油车登记证明平均每年节省256美元的燃料成本，每加仑燃料成本为4美元），这将有助于美国在这个汽车市场领域的竞争力。长期的社会影响将是提高车辆的燃油经济性，减少标准污染物的排放（例如，氮氧化物），从而减少车辆的碳足迹。此外，这项工作将增加调查人员？努力增加STEM学科中女性和代表性不足的学生，并通过利用用于STEM夏令营和课程重新设计活动的资源来改善本科生热力学课程教学。最后，将传播学术文章和会议报告，以确保科学和技术途径的发现被人所知。

This PFI: AIR Technology Translation project focuses on translating the synergistic combination of low heat rejection (LHR) and low temperature combustion (LTC) to fill the technological gap between existing commercially available internal combustion engines and the clean high-efficiency advanced combustion engine. The translated LHR/LTC technology has the following unique feature: low heat rejection from a low temperature combustion engine that results in more favorable thermodynamics compared to either conventional or ordinary low temperature combustion engines. This provides exemplary efficiency, engine-out exhaust emissions of nitrogen oxides and fixed carbon, and suitable exhaust temperatures for favorable operation of exhaust emission control systems when compared to the leading competing internal combustion engine. The project accomplishes its objectives by performing a proof-of-concept that experimentally and computationally realizes LHR concepts with LTC in a compression ignition engine resulting in a prototype LHR/LTC combustion mode operating in a light-duty automotive diesel engine. The partnership engages General Motors, which engineers and manufacturers the prototype-intended light-duty automotive engine. GM provides guidance in the global automotive market space such as operating constraints, cost limitations, and technology integration with a marketable product in order to translate LHR/LTC combustion along a path that may result in a competitive commercial reality. The potential economic impact is expected to be nearly $40million in the next 10 years (based on new diesel vehicle registrations in the United States demonstrating on average $256/year in fuel cost savings at $4.00/gallon fuel cost), which will contribute to the U.S. competitiveness in this automotive market space. The societal impact, long term, will be improved vehicle fuel economy with reduced emission of criteria pollutants (e.g., nitrogen oxides), thereby reducing vehicle carbon footprint. Additionally, this effort will augment the investigators? efforts to increase female and underrepresented students in STEM disciplines and improve undergraduate student course instruction in thermodynamics by leveraging resources used for summer STEM camps and course redesign activities. Finally, scholarly articles and conference presentations will be disseminated to ensure scientific and technological pathway discoveries are made known.
